Front (Question)

How to carry out a Titration

Back (Answer)

• Measure a known volume of alkali into a flask using a volumetric pipette. Measure from the bottom of the Meniscus. • Add a few drops of indicator (phenolphthalein- Pink in alkali, colourless in acid) • Pour acid into a Burette. Drop into alkali until alkali changes colour. • Measure how much acid it took, an repeat until you get two identical results.
